Something like this may be of use to you:

quiz_names = ['a', 'b', 'c', 'd', 'e']

random_names = quiz_names.sort_by {|quiz_name| rand(0)}
puts random_names

--output:--
["b", "a", "e", "c", "d"]

You do not need the block parameter.

I know. I also don't need the parameter for rand(). However, both make
the code easier to follow--especially for someone new.

Ive basically made 6 quizes which are controllers from models. how do i
randomise them. Is it by making another model and a controller or is it
somewhere else.

Many thanks

Angelo
